INTERNAL-COMBUSTION ENGINE. 5

Application filed June 18, 1923. Serial No. 646,180.

The object of my invention is to produce a compact motor, preferably of the internal combustion type, though capable of usein connection with steam or other similar motive fluid.

The accompanyingdrawings illustrate.

my invention.

Fig. 1 is a side elevation of my improved motor, with portions in vertical sections, the upper left hand corner being a section on line 1 of Fig. 2, while the upper right hand portion is a section on line 1 of Fig. 2;

Fig. 2 is an elevation at right angles to Fig. 1, the upper part being in axial vertical section and a portion of the lower part being also in vertical section;

Fig. 3 a side elevation, on a smaller scale, and Fig. 4 an elevation opposite to that shown in Fig.

In the drawings 10 indicates a stationary casing having a circumferential annular chamber 11 having parallel ported opposed faces 12 and 13 between. which is fitted a rotary cylinder body let which is provided with parallel ported faces co-acting with the ported faces 12 and 13 and which is formed of a plurality of segments mated upon radial lines as indicated at 15.

In the present drawings 1 have shown the rotary cylinder body, or rotor, as formed of two mating segments, the engine being of a four cylinder type, but it will be readily understood that one or more pairs of additional cylinders may be provided, in which case the rotor will be composed of a correspondingly greater number of segments.

Formed in each roton segment are two cylinders 16 (only one cylinder of theseg ment being shown) said cylinders having their axes arranged tangentially to the axis of the rotor and having one end opening into a radial face of the segment, the ar rangeinentbeing such thattwo cylinders of mating rotor segments will lie end to end, as shown in Fig. 1. The two cylinders of each pair of cylinders are preferably arranged so that' their axes lie at an obtuse angle to each other, as indicated in Fig. 1,

for a purpose which will appear.

Mounted in each cylinder is a piston 17' provided with a pitman 18 and the two pitmen of adjacent pistons are pivotally connected to the outer end of a lever 19 pivoted at 20 in the rotor 14:.

The rotor 14- is connected to a shaft 21. journaled in suitable bearings, centrally, in the casing 10. Lever 19, between its fulcrum and outer end, is provided with two oppositely extending arms 22 and 23. Arm

.22 carries a cross-pin 24 which is projected through openings 25 formed through the side walls of the adjacent rotor segment and the outer ends of this cross-pincarry pairs of rollers 26 which, in the present drawings, are shown as supported upon roller bearings 27.

Similarly, arm 23 carries a cross-pin 28 projected through the side walls of the adjacent rotor segment and provided at its ends with pairs of rollers .29.-

Surrounding shaft 21, and carried by casing 10, are two cams 31 and 32 upon which rollers 26 and 29 ride. very slight variation, theoretically, between the proper cam which will always be cons tacted by the leading rollers 26, and a cam. which will always be contacted by the trail-- ing rollers 29, but for short piston strokes, the cams may be modified from theoreti 'al. correctness so as to co-act with both such rollers. If desired, however, the two cams may be formed with two slightly ditferei'it tracks of such characttnthatson'le of the rollers of each set will contact with the. cam during the strokes of their pistons in one direction, while the other rollers of the set will contact with the cam. during the otherstrokes of their pistons.

There a The ports 35, through wall 12, are inlet.

The side walls of the rotor, within the I .annularchamber 11, are continuous, exceptfor the ports 40, one for each cylinder, leading into the outer end of the cylinder, and each of said ports is suitably protected by packing rings 41 conveniently in the manner disclosed in my re-issued patent No. 14,347.

Motive force is applied alternately to the pistons of each pair of cylinders and the cams 31 and 32 are so designed that motive force applied to the trailing piston of each pair will drive the rollers 26 inwardly and forwardly upon the cams so as to cause the rotor to be drawn forwardly in the direction indicated by the arrow in Fig. 1. h/Iotive force applied to the leading piston of each pair will drive-the trailing rollers 29 inwardly upon the cams, thereby exerting a forward push upon the rotor body. If a motive fluid such as steam is used, it will be apparent that rollers 29 and 26 will exert alternate pulls and pushes upon the cams and rotor to cause continuous rotation of the rotor, whereas, if an explosive motive fluid is used, it will be apparent that, immediately following the exertion of force upon the cams through rollers 26, continued rotation of the rotor, under the momentum of the parts, will cause rollers 26 to be swung outwardly by the cams so as to produce suction in the leading cylinder of the pair under consideration and exhaust in the trailing cylinder of that pair. Ultimately, explosion in the leading cylinder of a pair will cause co-action between rollers 29 and the cams, in the manner already described, to exert a propulsive force upon the rotor. By setting the axes of each pair of cylinders at an obtuse angle, as indicated in Fig. 1, the power exerted upon the lever 19 by each of the pistons, at the beginning of the power stroke is substantially at right angles to the lever.

I claim as my invention:

1. In an engine, the combination of a shaft, a cylinder body carried by said shaft and provided with a pair of cylinders, each of which is arranged substantially perpendicular to a radius of the rotor and ported laterally for the induction and eduction of motiveiluid, pistons mounted in the cylinders of said cylinder body, a lever pivoted in the cylinder body and connected to said pair of pistons, a casing enclosing said cylinder body and co-act-ing with the ports thereof, said casing having induction and eduction ports co-acting with the ports of the cylinder body, two cam-engaging elements carried by ,said lever, and cams carried by the casing and engaged by said two cam-engaging elements.

2.
